It is believed that the presence of certain trace elements in the skin may play an important role in the formation of melanomas. In this work, neutron activation analysis and x-ray fluorescence analysis were used to determine trace element concentrations in cancerous, noncancerous and normal swine skin samples and in non-cancerous and normal swine tissue samples. In-vivo x-ray fluorescence analysis was also used to determine trace element concentrations in cancerous, non-cancerous, and normal swine skin. Data on forty-eight trace elements in each sample were obtained and correlated. The limited number of cancerous samples made definitive conclusions about trace element imbalances uncertain. Nevertheless, the in-vivo XRFA method was shown to be a very useful method for trace element determination. Additionally, good base line data were obtained for trace element concentrations in a variety of organs of Sinclair miniature swine. / Master of Science
